B1007 MERCURY MeaningThe Steering Column Control Module (SCCM) monitors input from the multifunction and headlamp switches. When the headlamp switch is in the HEADLAMPS ON position and the multifunction switch is placed in the HIGH BEAM position, the SCCM sends a message to the Body Control Module (BCM) over the High Speed Controller Area Network (HS-CAN), indicating a high beam request. The BCM then provides voltage to the high beams. The BCM provides an overload protection of the high beam output circuits. When an excessive current draw is detected, the BCM disables the affected high beam circuit driver. The Instrument Panel Cluster (IPC) also receives a message over the HS-CAN to illuminate the high beam indicator when a request for the high beams is received. This DTC sets when the SCCM detects a fault from the multifunction switch input.
